10.
MCQ has 18 possible answer, only 1 is correct.
If its a guess, then we say that we are randomly answering the question.
So, probability of getting the answer correct is 1 out of 18 ( as there are 18 choices out of which 1 is correct) = 1/18
Now, 1/18 is more than .05 ( the cutoff of significance for an event)
Since 1/18 > 1/20 (.05), we say that this event is not significant as probability s more than .05
hence, answer is NO
